[2020] Morello confirms that the person responsible for the ranking system in Valorant is no longer working with the company. Riot are actively working to design a new system but the current system is "unowned."

This is not correct, and some of the comments below are more accurate. The lead designer behind the current ranked system has left, but there are plenty of people still on the team who understand it both technically and from a design standpoint.

The feature has a temporary design owner, and we're actively sorting out 1) who will take over the design long term and 2) what changes need to happen next.

This has been made out to be more dire than it is.
